THE GOLDEN RULES OF RADIO LANGUAGE

​

1. Slow Down and Wait

In children with CVI, there is a distinct period of visual latency between the moment an image reaches the brain and the moment it is interpreted. This rule aims to provide the "silent gap" required for the child’s brain to process data.

• Silent Waiting: When you present a toy or ask a question, wait silently for at least one minute without any intervention or repetition. Rapid repetitions increase the cognitive load on "the printer" (the occipital lobe), which can lead to the system becoming overwhelmed or "saturated".

• Stretch Your Words: When speaking, do not merely slow your pace; prolong the pronunciation of vowels and consonants. Instead of saying "Look, a ball," adopt a rhythmic and drawn-out speaking style, such as "H-e-r-e... i-s... a... r-o-u-n-d... b-a-l-l... f-o-r... y-o-u".

• Respect Fatigue: Double this wait time when the child is tired, hungry, or stressed, as visual processing speeds slow down even further under these conditions.

​

2. Simplicity 

Complex sentences impede the "General Manager's" (the Frontal Lobe) ability to filter information. The objective is to emphasize only the key word associated with the current action.

• Single-Word Labeling: Label the experience by naming the object at the precise moment the child touches or views it. For instance, when the child picks up an apple, name the experience by simply saying "APPLE," instead of "Look at this beautiful red apple, let's eat it."

• Build Upon the Known: To support language development, present a known word before adding a new action. If the child knows the word "milk," expand the phrase to "Milk-drink," always placing the familiar word at the beginning of the sentence.

• Separate Visual and Auditory Inputs: Cease speaking entirely while the child is attempting to focus visually. Children with CVI often find it difficult to focus on looking and listening simultaneously; closing one sensory channel (remaining silent) facilitates their ability to focus.

​

3. Priming / Advance Preparation 

This rule aims to reduce uncertainty-induced stress and visual fatigue by creating a "preview" in the child's mind.

• Establish a Tactile Bridge: Before requesting the child to look at an object, allow them to hold and feel its temperature and texture. This creates a record in the brain's "visual library" (the temporal lobe), ensuring the child knows what to expect before they search visually.

• Step-by-Step Navigation: Provide auditory warnings when moving or approaching a hazard. For example, prepare them by saying, "There is a step in three paces," or by using a light touch on the shoulder.

• Initiate Routines with Sound: Introduce the relevant object through sound or smell before starting routines like bathing or eating. Let them hear the sound of the toothbrush or smell the toothpaste; this allows the child to predict the next step, fostering a sense of security.

• Identify Yourself: Always announce your presence verbally whenever you enter the room or approach the child: "Hi Ahmet, it's Mom; I'm coming closer and I'm going to hold your hand." This prevents the child from being startled by sudden visual changes in their environment.

IMPORTANT NOTE: It is vital to cease speaking entirely once your child focuses on a visual object or scene. Information arriving simultaneously from multiple sensory channels can lead to cognitive overload, resulting in rapid mental fatigue, irritability, or a complete 'visual shutdown'.

​

If your child averts their gaze while you are speaking, this does not signify a rejection. On the contrary, it is a purposeful strategy to eliminate 'visual noise' in order to focus more effectively on the auditory information being received.

​

Therefore, throughout the habilitation process, adopt the principle of 'explain first, then show silently.' Remember to provide the 'silent gap' your child requires for exploration; sometimes, the most profound support you can offer is your silence."

​

PREVENTING FAULTY LANGUAGE DEVELOPMENT (ECHOLALIA)

Visually referenced phrases frequently used by parents, such as "Look!" or "Come here," find no equivalent in the child's world because they cannot see what is being referred to. This situation can lead the child to believe that it is normal to use language without meaning, which predisposes them to echolalia—the repetition of words they do not comprehend. Radio language mitigates this risk by providing the child with a communication style that is exclusively accessible and grounded in their own experience.
